Barosaurus lentus (Sundance Sea Stratigraphy) Lyrics

Stratigraphic zones two to five
composite term Barys and Saurus
early Tithonian stage of the Jurassic
in the floodplains of the ancient Sundance Sea

the structure of the cervical vertebrae
allowed lateral flexibility but restricted vertical
it swept its neck in long arcs at ground level
moderate blood pressure, radiating excess body heat

the longest neck and the longest tail
the chevron bones lining the underside
forked with a prominent forward spike
protruding neural spines not complex

dorsal into cervical, column never found
peglike teeth confined to the front of the jaw
a single carpal bone in the wrist
digitigrade, manus adorned with a large claw
